<span>Eating away from home is playing an increasing large role in the diet and the household budgets of American families. Back in 1970 approximately 26 percent of all food spending was on food away from home; by 2012, that amount had risen to 43 percent. The increase can be attributed to a greater percentage of women employed outside the home, more two-earner households with the resulting higher incomes, as well as more affordable and convenient fast food outlets.

Answer: A fern gametophyte produces eggs and sperm in archegonium portion and antheridium portion respectively
Ferns are bisexual and go under sexual reproduction. Ferns reproduce by using spores. In haploid phase each of the cells contain only one copy of each chromosome and in the multicellular diploid phase where each of the cell contained two copies of each chromosomes.
The sperms are produced in the antheridium portion and the eggs are produced in the archegonium portion
Answer:
The correct answer will be- red blood cells (RBC)
Explanation:
Malaria has proved endemic to the human species as it has killed the humans in large numbers and it has acted as one of the strongest selective force.
The malaria disease has caused the mutation in the genes in the red blood cells which carries the oxygen to different organs of the body. The mutation in the genes causes the circular shape of red blood cell to sickle-shaped cells which carry less oxygen to the organs.
The change in the shape of red blood cell provides resistance against malaria disease but it becomes a problem where malaria is not a problem.
Thus, red blood cells (RBC) is the correct answer.
